Resrouces for food safe letter stamping options for cookies?

I'm looking for a food safe letter stamping kit for cookies to stamp custom messages or names into cookies. I've only found a cheap, plastic consumer grade kit that is a nightmare to assemble. The letters get stuck. Way too much of a time waste.

Any recommendations? I'd like to set up the words and stamp, not punch in each individual letter.

I am sure you have searched this on your own and have seen some of these already.

Cookie stamps (already made and usually purchased from private sources) are highly collectable, expensive and most likely useless for your needs.

Trying to patch random letters together and stamping is probably more work than you can charge for (altho with a steady hand you could do one letter at a time get an ok look if you don't die of boredom first lol).

Thanks Mimi! One of these from your link looks like it might actually pan out. I'm ordering and will see. If the letters don't get stuck (like the current product I'm using) I'll be happy to just be bored instead of frustrated and battling tiny little plastic letters. Thanks again.
